Are there ever days when you leave your soft contact lenses in for too long? It goes without saying that generally, things are just plain better when they haven't been used too much. The same can be used to understand the importance of changing your contacts. It's a bad idea to leave them in for any more time than you need to. Even though it might not seem so bad, if you want your eyes to see their very best, don't overlook the replacement routine given to you by your optometrist. So, if you're told to change pairs monthly, then change them every month, because they can't be worn any longer than that.
You might think to yourself, would it be so bad if I got a couple additional days out of them? To understand this idea, let's talk about protein - not the type you stir into your shakes, but the natural protein that is a main component of the tears and eye fluids that gradually accumulates on the surface of your lenses, forming a mild haze. Unclear vision is only the first symptom.
After some time, these proteins evolve and trick your immune system into thinking the accumulation is something foreign, and the body's reaction can lead to inflammation in the eye. And this means that a toll is taken on your vision. Even when you do all you can to take good care of your contact lenses, as time passes, they become less smooth and clear, just due to regular deterioration.
So basically, it's best to commit to the plan your optician determines for you. Everyone's eyes are different, so only your eye care professional should determine the appropriate contact lens replacement routine for you. If you change your contact lenses on schedule, you'll never notice the difference that is so obvious when you wear them for longer than you're supposed to.
